  One day they went for a walk early in the morning and met an old man. He lived on a farm, and he was sitting in the warm sun in front of his house. Mr. Green asked him, "Do you like to live in this quiet place?"
  The old man said, "Yes, I do."
  Mr. Green then asked, "What are the good things about it?"
  The old man answered, "Well, the people here know each other. They often come and visit me, and I often go and visit them. And there are also many children here." Mr. Green said, "That's interesting, and what are the bad things?"
